To al?, ywhom it 'may concern:

Be it known that I, GEORGE' Il. SCOTT, a citizen of the United States, and a resident of Poplar Bluff, in the county of Butler and State of Missouri, have invented-certain new and useful Improvements in Incubators, of which the following is a specification.

M v invention is an improvement in incubators, and consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed. i

In the drawings Figure l is a perspective yiew of an incubator embodying my invention. Fig. 2 is a vertical longitudinal section thereof, parts being shown in elevation. Fig. $3 is a vertical cross section on about the line 3 3 of Fig. 2. Fig. 4 is a erspective view showing some of the wor ing parts, parts being broken away, and the casing being indicated in dotted lines: Fig. 5 is a detail perspective view showing the end of the revolving egg holder shaft and the arm thereon. Fig. 6 is a sectional view of the egg carrier on about line 6-6 of Fig. 7. Fig. 7is a cross-section on about line 7 7 of4 Fig. 6. Fig. 8 is a detail perspective view of a portion of the egg carrier, and Fig. 9 is a detail perspective view showing a some-what different construction.

In carrying out my invention I provide a suitable casing A which may be mounted upon legs B, and be supplied with doors C and .D for permitting access to the lower heating compartment E, and the upper or egg compartment F. These compartments E and F may be separated from each other by a cross partition G which, as shown, may be of cot ton, canvas, or other suitable fabric and eX- tends from side to side within the casing and separates'the compartments E and F as will be understood from Figs. 2 and 3 of the drawings. In the lower compartment E is placed a pan or water holder E', and a heating space E2 in the form of a box or recess in the bottom of said pan E is rovided, as shown in Figs. 2, 3 and 4, in which the flame from the lamp not shown, or other suitable burner may be concentrated for heating thel water in the pan E. Suitable flues e2 lead from the heating box E2 laterally through the sides of the case and thence up to the to thereof, as shown, for carrying olf the pro ucts of combustion. The heat from the water in the pan E may circulate through the partition sheet G and thus heat the upper compartment F. Vater is supplied by a pipe from any suitable source, a valve e being provided for regulating the same for renewing the contents of the water pan E', and a turn-cock e may be arranged asl shown in Fig. 3 for drawing 0H the lcontents of the water pan when desired.

A Ventilating pipe I having suitable perforations i is disposed Within the compartment F at the bottom thereof, and preferably around the said compartment, as will be understood from Figs. 2, 3 and 4, for distributing fresh air supplied from the inlet pipes J communicating With the pipe I at the ends of the incubator through the openings J. The inlet pipes J are supplied with piston valves J 2 actuated by springs J 3, as shown in Fig. 2, the valves J2 operating across the openings J The valve J2 it will be noticed is a piston operating in a cylinder open at its outer end and actuated by or' under the influence of a spring J3, which will be compressed by thel movement of the piston' outwardly and eX- panded by the movement of the piston to-L ward the inner end of the cylinder. The cylinder in practice is about four inches long. Cold air enters the outer end of thev barrel or cylinder. When the incubator becomes heated the piston valve is gradually drawn in and opens up a space at J through which the cold air enters the ventilator I and thence into the egg holding space of the incubator.

-moved to a position to nearly uncover the opening J when the incubator is too hot and to close the said opening when the tempera ture of the incubator lowers, thus regulating the temperature as will be understood from Fig. 2 4of the drawing. Y y

It will be noticed from Fig. 2 that the openings J are at t-he bottom of the compartment F and as the heat naturally ascends, the draft will be inward through the openings J as long as the temperature is at say 1,03", which is the temperature ordinarily maintained in incubators. The draft woull therefore be inward through the openings The spring J3 is of very light wire and the The piston is delicate being of light material and the sprlng 1s of fine wlre,

Means are provided for actuating theegg carrier ste by stepand reference water operated devices are provi ed for this pur- To this end l provide a bucket M slidingvertically in suitable guides M on `the casing, and provided at its lowerV end With a cock ,or aucet,N Whose handle N is tripped by a projection a 'when the bucket M is in its lowermost position, and it is opened.

to discharge the contents of the bucket M and is tripped in its uppermost position by a projectionza when the bucket 'is in its up permost position to close said cock or faucet as will be understood from Figs. l and 4 of the drawings. Thisbucket is connected by a chain O with the swinging arm L and ,the 4'said arm is connected by a chain O with a spring P above the said arm and it may be guided by a guide pulley P, as shown. The purpose of this spring P is to readjust or lift the bucket M when the' latter has been emptied, and. a drip device Qwhich may be in connection `with the city service or other source of water supply, is arranged. to drip water slowly into the bucket M so that when the latter has been lifterflto the position shown in Fig. 1, and its valve closed by the projection cL, the drip ol water will'gradually lill the bucket, and the latter will lower to the position shown in Fig. 4, meanwhile giving a partialA revolution to the shaft K, and the egg carriers thereon, as is desired. Vilhen the bucket M reaches its' lowermost position, as shown in Fig; 4, its valve will be o ened by' engagement with the projection a, the contents of the bucket V77will be discharged, and the bucket will then be readjusted by the spring P to the position shown in Fig. 1, and then will be gradually moved from said. position to that shown-1n Fig. 4, as the weight of the bucket gradually over comes the action of the spring P, the egg carrier being thus slowly turned so that the eggs will v' be turned gradually and without with two cross plates R spaced apart.l One and 4, that the projection A will not turn 70 the handle N of the valve to a vertical position, but will turn it to an inclined position so that when .it lowers and comes in contactl with the projection a, the handle of the valve will be turned out to the position shown in Fig. 4, opening the valve to permit the water to escape.

As best shown in Figs. 6, 7 and 8 the egg holder is in circular-forni and is provided with circular series of pockets R for the eggs, saidv pockets being shown as short cylinders secured at one end to circular plates R by rivets or otherwise, open at their other ends and provided at said open ends with inwardly projecting'annular iianges R2, tol prevent the eggs from rolling' out.

As shown in Fig. 2, I make the holder in Asections secured along the shaft K, each section being constructed as shown in Fig. 6

series of pockets R is secured to one of the plates R', .while the other plate R has 'pockets secured on` both sides, as best shown in Fig. 6, the pockets of two of the -series opening toward each other as shown in Fig. 6, the open ends of' the opposite pockets being connected by inner and outer wire gauze sections S' and S', as shown in Fig. 7.' The pockets maybe formed of plate material, as shown in Figs. 6, 7 and 8, or they may be of 100 wire gauze, as shown in Fig. 9. The eggs may be readily placed inand removed from the pockets and any suitable number of sections such as shown in Fig. 2 may be .supplied along the vshaft K. ,Y

It vwill be noticed from Fig. 7 that the wire gauze sections S' and S are in the forni of segments of cylinders, and they inclose between them rnost of the pockets of the outer circular series.

In Fig. 2 the wire gauze is partly broken away so that some of the cells are shown in side view. i

S, S Fig. 7, shows wire netting projecting out between the egg cells and extending around ythe row of cells eXAcept'for an opening at. one side. This wire netting is about two inches wide and when the other egg cells are shoved up to the wire it brings the adjacent sets of cells comparatively close together, see Fig. 6. This allowsk the chicks to come out between the outer and inner sections of wire netting and when the shaft is thrust around withthe ol'iening at the bottdm the chicks can fall out without injlury ontoithe 'canvas 125 that separates the lower from the upper parts. This arrangement is more especially designed for incubators of large size, say in an egg holder holding 150 eggs chicks instead of slipping out and falling straight down can holder,
